The proper way to watch grappling is to boo and yell "STAND THEM UP" at your TV if they've been on the floor longer than .02s without a KO.

I thought the proper way to watch grappling is to stand with your back to the cage, beer in hand, and scream into the camera as it pans the crowd. Advanced grappling watchers also get into drunken fights in the parking lot after the event.
